Sentei no Oni resembled a giant insect with vague humanoid features. The body was segmented with hundreds of massive legs moving its even bigger body. It used its first four or five pairs of legs as arms, rearing up to grasp at it's enemies. [3]

Sentei no Oni was considered possibly the most dangerous of Shokansuru's creations, as it appeared to be impossible to destroy it. It had better regenerative powers than nearly every other creature in the Shadowlands, and even if it was believed to have been killed, a tiny portion surviving would mean the creature would return to life sooner or later. In battles the creature charged directly at it's enemies, attempting to trample them. Failing that it reared up and attempts to grapple them. [3]
